Hi. I am 21. I have been with my boyfriend for 6 months, and we are in a monogamous sexual relationship. We had sex this morning, and it got kind of rough towards the end. After we finished, I noticed my vagina ached. After I showered, it was still hurting, so I looked and I have two bumps that appear to be blisters on the opening to my vagina. The pain has gone away since then, and I don't have pain when I urinate either. However, I am terrified that these are a symptom of a STD (herpes??). I am really scared. Does anyone know if you can end up with blisters from the friction of sex? I can't find any information online about blisters besides that they are a symptom of herpes, and so now I'm freaking out thinking I have herpes. I'm going to schedule an appointment with the gyno tomorrow, but until I can get in to see her, if anyone knows anything about this, I'd really appreciate the insight! Thanks...
